Home of the Original STETZERiZER® Filter

Over the past decade, Dave Stetzer has focused on troubleshooting power quality problems, specifically the problem of dirty electricity (electrical pollution, “stray voltage”), in the United States and in numerous countries throughout the world. His work in this area led to the development of the STETZERiZER® Filter, the world’s first power line EM (electromagnetic) filter.
